Wherever I dig, front garden or rear garden, at a depth of 300/400mm or so, I always find a thick layer of this ugly stuff.
It's not just for the inspection chamber, this stuff is everywhere!
It looks like old road scalpings. It's certainly tar covered rock of some sort.
Property was built c1993
Lawn often collects puddles, suffers from lousy drainage.
Getting anything into the ground to a sensible depth is a tough challenge.
Why did they do this, what's it for?
Thank you.

Most likely was cheapest way to build the levels up

I dug out over a foot thick layer of quarry dust covering the entire area under a 'lawn' on a new build last year. It was the last house of a terrace and so they obviously just threw whatever they had left in it.
Yet to work on a new build and not find something weird buried. Inc radiators, a concrete sewer ring and of course the classic steel block bands

worked for loads of blokes whose motto is
"dig a big hole and bury it"

the amount of home owners that want to bury asbestos is incredible!

It's pretty safe when buried, its not a chemical it's a mineral so doesn't pollute water etc its only lethal as a dust in the lungs
The brake factory we are at buried over 1000s tons of it in an old quarry and capped it with a few metres of clay

yeah but still a pain in the arris if you are the guy who smashes it all up with a machine trying to dig footings ten years later.

correct dan
we redid our asbestos course last week and deaths from it are peaking now
40 tradesmen ,9 electricians and 3 plumbers are dying every week from it
these were blokes on site in the 60- 70-80-90s
one exposure can cause mesothelioma,
its costing us £1200 to get the garage ceiling removed on the job we are on, but whoever fitted the guys new garage door last year drilled 8 screws through it to fix his brackets
our tutor on the course informed us that the HSE are prosecuting in every case of asbestos abuse,no exceptions
million pound fine
however you can remove asbestos on your own home,but who wants to?

There are asbestos specialist in full time at the factory, they go in first before anyone and Hoover all the dust, spray a glue like spray over everything to prevent dust then the other trades can start, they wear disposable boiler suits they have 4 colours for the risk and go from from good dust mask to full face respirators.
They've got a trailer parked up with showers in that they go in before taking the boiler suit off, it's not worth the risk to mess with it.
Lad I know wants me to dig his footing but get rid of his asbetous garage albeit asbetous concrete sheets are only 5% asbetous but still I've told him I'm not getting involved
White and blue powdered asbetous is the worst when applied as a wet paste and wrapped in denso like fabric tape rd pipes.
Ferodo the company we are working for went busy because they had to put £8bn in fund to pay out on asbetous cases, they were the first company to use it in brake linings

if you smoke the risks are a lot higher

50 times higher rab
apparently if you smoke the minute hairs in your esophagus get flattened,which means the asbestos fibres can get straight into your lungs
our course tutor steve mobius (great guy BTW) worked making big six sheets in the 70s for eternit in royston
all his coworkers are dead or dying
he NEVER smoked at the time
